What is a GBC

So what is a GBC?

I GBC is a lego contraption that moves balls! That could be a conveyor a lifter, and down-hill track, trains, or anything that moves balls. GBC's will usually do the job automatically (i.e. You don't have to load the train or you don't have to spin the lifter up and down). That is usually what makes the GBC hard. Pistons and other cool mechanisms are used to automatically to lift, spin move and even clean the balls as they pass through on a track

There are many examples! Cup to cup, elevator , lifter triggered by a stuck ball , on and off the train, basket shooter, grap and release ball factory. You can view some here:


Lego GBC's can usually be combined so that they work together! Or if you have one GBC, you can make a track that makes the balls run back to the start! Read more information in my other topics if you want to find out more
